Sudden drop in MPG?

im getting 210 miles per 16 gallons, is there a way I can get up to at least 19 or 16pmg?

 

Depends, what's your taco's specs? V6 or I4? Manual or auto? 4x2 or 4x4? What maintenance or repairs have been done?

 

Tune up, take any mods back to stock, adjust your driving style.

That is about the long and short of how to improve mpg in any vehicle ever made. Driving style is about 85% of any changes made

 

^^^^ Truth.

 

Changed my spark plug wires really helped. Before I was getting 12-13 mpg on highway and after I got about 15-17 mpg. First time changing the plugs at 169k lol... I went with Ngk plugs from Amazon

 

its sc changed all oils sythentic high grade

 

If it makes you feel better im in gretna so within 30ish miles of you. Both my truck and my parents dropped a few mpg so i wouldnt rule out the winter blend

 

Still better than my 16 mpg on a good tank in my 4banger with an empty bed
